Jore: A cribbing horse with a collar is only as good as the collar and the amount of work he gets. The advice above they are giving you a very good except I do have to take issue with the comment on Equiotic. This Equine Bacteria Technology was tested on hundreds of horses and the only way it could possibly cause colic is if the packets or paste was left in the heat and spoiled. It says on the packaging to keep cool. I keep it in a refrigerator.
If the hind gut is compromised, you need what was in it in the first place. Namely equine bacteria that is the sub-strain from the horse. That is Equiotic with it's Lactobacillus reuteri. The big difference between this product and the super laxative/probiotics that you see on the market is that because Equiotic is made from actual equine bacteria it is actually reactive with the creation and growth of reuteri/metabolite which kill pathogens and stimulate the receptors in the mucosa. While walkinthewalk
is obviously an experienced and more than responsible horseman, I would take a guess that his vet did not tell him to put the Equiotic in the fridge. If I am wrong, I would love to know it and I do not doubt his word in that he only wants what is good for your or his horse but, I use a TON of this product and know what it does. It went to London with the USEF Eventing team and is at the World Championship Endurance Championships on every single horse on the USEF team.
If it is a good horse and you can put up with the cribbing and will give the horse a ton of work, it could be worth it. I have been around world class Jumpers and Dressage horses that were cribbers. As with most horses, it is a matter of management no matter what.
